Competitive tournaments are organized events where individuals or teams compete against each other in various sports or games. These tournaments can take place at different levels, from local competitions to international championships. Participants aim to win by showcasing their skills, strategy, and teamwork, often leading to rankings or prizes. Tournaments can follow different formats, such as single-elimination, double-elimination, or round-robin. In a single-elimination tournament, a participant is eliminated after a loss, while a round-robin format allows each participant to compete against all others. Popular examples of competitive tournaments include the FIFA World Cup in soccer and the NCAA March Madness in basketball.
